High-Performance Air Pressure Regulator Series

The Precision Controls Division of Marsh Bellofram Corp. launched the Type 41 high-performance air pressure regulator series, which is designed to support a variety of demanding industrial and original equipment manufacturer flow-monitoring requirements. Available in two different packages with identical performance characteristics, both with ¼-inch NPT BSPT port size, the Type 41 incorporates a patented Bellofram rolling diaphragm for greater sensitivity, improved accuracy, low-friction operation, and extended useful service life, all in a compact size. The Type 41 incorporates precision die-cast aluminum housings finished with scratch- and weather-resistant vinyl paint to increase resistance to harsh environmental conditions. Units are pressure- and chromate-treated for internal corrosion resistance. A rubberized, soft-seat valve stem provides stability and “forgives” dirt and other foreign matter. An aspirator maintains downstream pressure and compensates for droop when high flow occurs. The gauge port is convenient for installation and can also be used as an additional full-flow outlet. Users can select from among pipe, panel, or bracket mounting options. (
